The invention discloses a new-material surface scratch detecting platform and belongs to the field of new-material performance detecting equipment. The new-material surface scratch detecting platformcomprises a base, a new-material positioning device, a reciprocating scratching device and a gear motor and is characterized in that the upper end of the base is provided with the new-material positioning device; the reciprocating scratching device is arranged at the right end of the new-material positioning device; the gear motor is arranged at the rear end of the reciprocating scratching device.The new-material surface scratch detecting platform has the advantages that the platform is reasonable in design, convenient to operate and ingenious in structure; by the aid of an intermittent gear,a motor only needs to rotate in one direction to achieve reciprocating scratching, high scratching efficiency is achieved, and the new-material positioning device can be replaced according to the thickness of different new materials to guaranteed scratching pressure; the platform is simple in structure, low in production cost, small in size and convenient to take, carry and move; an adjustable conical tool bit is added to the platform, the height of conical tool bit can be directly adjusted according to the thickness of the new materials, and convenience is achieved.
